5 Basit Teknikleri için Telgraf kim icat ettiMorse code saf been in use for more than 160 years—longer than any other electrical coding system. What is called Morse code today is actually somewhat different from what was originally developed by Vail and Morse. The çağdaş International Morse code, or continental code, was created by Friedrich Clemens Gerke in 1848 and initially used for telegraphy between Hamburg and Cuxhaven in Germany. Gerke changed nearly half of the alphabet and all of the numerals, providing the foundation for the modern form of the code.

All Morse code elements depend on the dot length. A dash is the length of 3 dots, and spacings are specified in number of dot lengths. An unambiguous method of specifying the transmission speed is to specify the dot duration birli, for example, 50 milliseconds.
Malgrado la svogliatezza di fondo, Morse si laureò comunque presso il collegio di Yale nel 1810, mentre l'anno dopo si recò a Londra dove intraprese sempre più seriamente lo studio della pittura. Tornato negli Stati Uniti nel 1815, una decina di anni dopo fondò con altri artisti la "Società di belle arti" e successivamente la "National Accademy of Design".
” Before his death, Samuel Morse wrote, “The nearer I approach to the end of my pilgrimage, the clearer is the evidence of the divine origin of the Bible, the grandeur and sublimity of God's remedy for fallen man are more appreciated, and the future is illumined with hope and joy.”
The Morse system for telegraphy, which was first used in about 1844, was designed to make indentations on a paper tape when electric currents were received. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape. When an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape. When the current was interrupted, a spring retracted the stylus and that portion of the moving tape remained unmarked. Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages.
When Morse code was adapted to radio communication, the dots and dashes were sent kakım short and long tone pulses. It was later found that people become more proficient at receiving Morse code when it is taught birli a language that is heard, instead of one read from a page.
Morse had formulated the rudiments of the telegraphic alphabet, or Morse Code, kakım it is known today. He was incele ready to sınav his invention.

In 1848, Morse had married Sarah Griswold, with whom he had four children, and after he was recognized kakım the “inventor of the telegraph,” he settled down to a life of wealth, philanthropy and family. Morse grew a long beard that turned white, giving him the appearance of a wise sage.
In the gallery of the Senate, Samuel Morse had sat all the last day and evening of the session. At midnight the session would close. Assured by his friends that there was no possibility of the bill being reached, he left the Capitol and retired to his room at the hotel, broken-hearted.
